Case 721G Wheel Loader – Parts, Specs

Description:

Serial Number Location:

For Case 721G models (introduced in 2017 and still in production), the serial number plate is typically located on the left side of the machine near the articulation joint, just above the front axle and behind the front left tire. Always verify the serial number before ordering parts, especially to confirm compatibility with emissions tier versions and electronic controls.

Common Issues & Fixes

Hydraulic Leaks Near Loader Arms: Inspect high-pressure hoses and replace with updated assemblies. Be sure to route hoses properly to prevent abrasion.

Intermittent Cab Display Loss: Usually caused by loose CAN connections—check behind the display and reseat all wiring.

Brake Pedal Resistance: Often a sign of air or failure in the brake accumulator—bleed system and inspect for internal leaks.

Overheating in Dusty Environments: Clean the cooling pack frequently and inspect fan drive system for faults.

Stiff Shifting in Cold Starts: Allow proper warm-up time and inspect shift solenoids for moisture-related faults.

Premature Tire Wear: Keep tire pressure within spec and rotate regularly; misalignment due to heavy loads can accelerate wear.
